tests: Verify TDLS responder teardown in encrypted network

Browse source 
Older mac80211 implementations did not set the link identifier
appropriately, resulting in an incorrect teardown packet being sent the
peer. wpa_supplicant adds the FTE containing the MIC field calculated
using the correct link-identifier. This causes a MIC failure on the
other side and the teardown is discarded. Verify this case is fixed by
newer kernel and wpa_supplicant code.
